DISCHARGING DEVICE FOR VERTICAL RETORTS.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed January 1c, 1914. Serial No. 812,400.

To all whom it may concern:

Be it known that I, PIERRE PLANTINGA, a & citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Discharging Devices for Vertical Retorts, of which the following is a specification,- the principle of the invention 1 being herein explained and the best mode in which I hdVBCOIItBHlPlfllEd applying that principle, so as to distinguish it from other inventions. A

My invention relates to discharging dcvices for vertical retorts used in the manu- 1 tacture of gas, its object bein to provide a device of said character which may be economically manufactured and which will perform its function in a satisfactory and efiicient manner.

The said invention consists of means herel inafter fully described and particular y set forth in the claims. l

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawings :--Figure 1 represents a vertical transverse section of the lower end of a retort and my improved discharging device attached thereto. Fig. 2 represents a longitudinal fragmentary section of the parts shown in Fig. 1. Fig. 3 represents a horizontal section of the discharging dcvice taken upon the plane 1ndicated by line Ill-III in Fig. 1. Fig. 4 represents a fragmentary transverse section ustrating a modified form thereof. Fig. 5 represents a vertical transverse section of the lower end of a retort and with a modified form of my improved discharging device attached thereto. Fig. 6- represents ahorizontal section taken upon the lanes indicated by lines VI-VI in Fig. 5. Fig. 7 represents a longitudinal axial section of the parts shown in Fig. 5.

Referrin first to that form of the device illustrated y Figs. 1 2 and 3, the illustrated embodiment of my invention comprises a gas-tight casing 1, having an inclined bottom 2 terminating at an opening 3 provided with a suitable closure 4, thro h which 0 ening the coke from the retort a ter being discharged may be removed. The upper end of the casing is secured to the lower end of the retort in a gas-tight manner and is provided with an opening 5 which registers with the lower end of the retort chamber 6.

l Formed in the rear of the casing and-below the Saidcpening 5 is a downwardly and inwardly inclined surface 7, the lower end of which pro ects inwardly a short distance beyond the rear wall 8 of the casing as at 9. liiimediately below the lower end portion of the inclined surface 7 is a series of alined recesses 10 through the walls of which passes a supporting rod 11 the extremities of which are supported in the end walls 12, 12, of the casing. Supported in suitable bearings 13, 13, secured to or formed integrally with the end walls 12, 12, is a shaft 14 parallel with the rod 11 and having its axis in a plane somewhat below the extremity 9 of the inclined surface 7. Mounted upon this shaft and rotatably secured thereto in. a suitable manner is a plurality of hubs 15,

each of which is provided with radially extending blades 16. These blades are arranged helically with reference to each other and in, the longitudinal direction of the shaft, as is the usual custom in this class of devices. As illustrated, there is an odd number of sets of blades and the middle three sets may be conveniently mounted upon a single hub. Each of the other hubs is formed with a circular cam 17 and similar cams 17, 17 are formed upon the middle hub. All of the hubs on the right-hand side of'the middle set of blades 16 are timed so as to reach their highest points successively and those on the right-hand side thereof are similarly timed. The number of recesses 10 corresponds with the number of the spaces between adjacent sets of arms and these recesses are in transverse alinement with said spaces. Having one end osoillatorily mounted upon the rod 11 and in each recess is an agitator-arm 18, the inner and free end of which extends into the alined spaces between thecorrespondingladjacent sets of blades 16 and rests upon t e correspondin cams 17, as shown in Fig. 1. One end 0 the shaft 14 is provided with a driving pulley 19 by means of which the shaft, cams and arms may be rotated, as will be readily understood. Such rotation will efiect the non-synchronous oscillation of those agitator-arms 18 which are located on one side of the middle set of blades and a similar oscillation of those blades on the other side of said set.

The coke coming from the bottom of the the said arms 16 revolve, they catch andcarry theroke forwardly and discharge it into the bottom ofthe casing. The oscillation of the arms 18 tends to prevent the mass of coke from binding and facilitates the downward travel thereof toward the discharging arms. By timing the circular cams differently as described, the power which it is necessary to exert to effect the oscillation, is distributed throughout one complete revolution of the shaft and thereby produces a more satisfactory operation, as Wlll be readily understood.

By employing the circular cams shown, the oscillation of the agitating arms is of a continuous and even nature. It may be desirable in some cases to eflect this oscillation in an intermittent manner and cause each one of the arms 18 to rise quickly and drop quickly and'then remain in a condition of rest throughout the remainder of the shafts revolution. Where such action isdesired, the shape of the cam may be varied to effect a quick riseand fall, as shown in Flg. 4, and a shelf or stop 20 may be formed on or secured to the rear wall and under each of such agitator-arms. The height of each of these shelves is made such that it will support the corresponding arm throughout a portion of the revolution of the cam and permit it to remain at rest for a period of time, is will be readily understood.

-The above described construction may be modified," as shown in Figs. 5 to 7 inclusive, by making a single recess 10 belowthe lower end of the inclined surface 7 and providing a plate 21, one end of which is oscillatorily mounted upon the rod 11 passing through such'recess and the other end of which is cut out to form a plurality of agitator-arms 22, each one extending between two adjacent sets of blades 16, as shown in Fig. 6. This construction would require a modification of the timing of the cams inasmuch asall of them would have to be arranged to operate upon the arms 22 simultaneously, as shown in Fig. 7.

As will be readily understood, the structures above-described may be varied in so far as concerns the number of sets of blades and cams employed in the timing of the latter without departing from the spirit of my invention.

In a discharging device for vertical retorts, the combination of a casing having an opening communicating with the said retort and provided with an interior downwardly inclined surface below same; a dis: charging member mounted in said casing;
